Just a small addition to the various answers

It would be helpful if you specified on with Operating System you are, 
because [shell] is heavily OS dependent (I'm guessing Windows, but I may 
be wrong)

A different strategy might also be to actually *not* delete files from 
within Pd, but outside, befor or after you close your patch. This is 
easily accoplished e.g. by a script.

Also a suggestion would be to give the temporary files very eloquent 
names such as 'TEMP_FILE_TO_DELETE_0001.wav' etc. and (whichever way you 
decide to do it) delete specifically *those* files instead of e.g. the 
whole directory, so e.g. instead of:

rm -f ./dir_to_delete/*

something like

rm -f ./dir_to_delete/TEMP_FILE_TO_DELETE_*.wav'

In my humble opinion it makes it more obvious what you want to delete, 
and (hopefully) less error/disaster prone (ok.. I've been bit by 
accidentally deleting files with no back up)
